Network virtualization has been proposed as a powerful vehicle for running multiple customized networks on a shared infrastructure. Virtual network embedding is a critical step for network virtualization that deals with efficient mapping of virtual nodes and virtual links onto the substrate network resources. Previous work in virtual network embedding primarily focused on designing heuristic algorithms...
The ever-growing creation of data requires large-scale network storage systems. One of the key issues related such systems is how to place several petabytes of data among large number of devices. Itpsilas necessary to design a reliable, fair, adaptable data placement algorithm. All proposed approaches are oblivious to the reliability-based requirements of data in such systems. In this paper, we present...
